Which of the following is not spread by droplet method?

Options

A. Tuberculosis
B. Diphtheria
C. Pertussis
D. Gonorrhoea

Answer

To determine which of the following diseases is not spread by the droplet method, we need to analyze each option provided:

1. **Tuberculosis (TB)**: This is an infectious disease caused by the bacterium Mycobacterium tuberculosis. TB is primarily spread through the air when a person with active TB coughs, sneezes, or talks, releasing droplets that can be inhaled by others. Therefore, TB is spread by the droplet method.

2. **Diphtheria**: This is a bacterial infection caused by Corynebacterium diphtheriae. It is also spread through respiratory droplets when an infected person coughs or sneezes. Thus, diphtheria is spread by the droplet method.

3. **Pertussis (Whooping Cough)**: This is caused by the bacterium Bordetella pertussis and is known for causing severe coughing fits. Pertussis is transmitted through respiratory droplets when an infected person coughs or sneezes. Therefore, pertussis is spread by the droplet method.

4. **Gonorrhea**: This is a sexually transmitted disease caused by the bacterium Neisseria gonorrhoeae. Gonorrhea is primarily spread through sexual contact and is not transmitted through respiratory droplets. Hence, gonorrhea is not spread by the droplet method.

Based on this analysis, the disease that is not spread by the droplet method is:

**Answer: D. Gonorrhea**
